How can I remesh a curve that has been converted to mesh?
For this kind of work I would use the RobinBetts© method:

Import your svg, convert to mesh, simplify with X &gt; Limited Dissolve.
Create a plane in front of your object, subdivide it vertically (probably more that what I've done in my screenshot). Delete the faces of this plane to keep only the edges.
Use the Knife Tool project to project these vertical edges on your object.
Give some corrections to your object so that it has a non-too messy topology.
Bend it (with Simple Deform / Bend mode or other) it has what it needs in terms of vertical edges to bend nicely.
